SHEET COLLECTING AND ASSOCIATING .MECHANISM.

Application filed November 30, 1921. Serial No. 518,982.

To all LU/Z0777, it may concern:

Be it known that I, HOWARD M. BARBER, a citizen of the United States,and resident of Stonington, in the county of New London and State ofConnecticut, have invented a new and useful Improvement in SheetCollecting and Associating Mechanism, of which the following is aspecification.

The object of my invention is to provide 1 a novel sheet collecting andassociating mechanism in which the same feeding means may be employedfor introducing either covers or inserts, or both, to be combined withvarious paged products of the press, thereby obviating the necessity ofusing separate feeding means for the covers and inserts as hasheretofore been common.

A practical embodiment of my invention is represented in theaccompanying drawings, in which- Fig. 1 represents the mechanism in endelevation.

Fig. 2 represents a longitudinal vertical section with the side framesremoved.

Fig. 2 represents a detail longitudinal. vertical section through aportion of the mechanism in a different plane from Fig. 2.

Fig. 3 represents a longitudinal vertical section through the severalcylinders.

Fig. 4 represents the gearing connecting the several shafts.

Fig. 5 represents a cam half section, such as would be used to changethe two-lobed cams to one-lobed cams.

The side frames are denoted by 1 and 2. Portions of two extra sheetfeeding mecha nisms are represented by 3 and 4, each of which feedingmechanisms may be used for introducing either inserts or covers, as maybe desired. The transfer cylinders 5 and 6 have their shafts 7 and 8mounted in the side frames 1 and 2, the cylinder 6 being provided withhead grippers 9 arranged to take the extra sheets from the feeder 4.

The transfer cylinder 5 is provided with a set of head grippers 10 fortaking the extra sheets from the feeder 3 and it is also provided with aset of head grippers 11 for taking the extra sheets from the grippers 9of the cylinder 6 fed by the feeder 4.

The collecting cylinder 12 has its shaft 13 mounted in the side frames 1and 2, which cylinder is provided in the present instance with threesets of head grippers 14.

The collecting and associating cylinder 15 has its shaft 16 suitablymounted in' the side frames 1 and 2, which cylinder is herein shown asbeing provided with five sets of head grippers 17 and five sets of sidegrippers 18 alternating with the head grippers.

The delivery cylinder 19 has its shaft 20 from the cylinder 15 anddeliver the same to any suitable folding mechanism, not shown herein.

I have shown a pair of coacting rotary cutters 22, 23, arranged toreceive superimposed narrow webs from the press and to cut the sametransversely into groups of sheets which are fed between guides 24, 25to the coacting point between the cylinders 12 andl5, into position tobe taken by either the grippers 14 or the grippers 17, as the case maybe. These rotary cutters have geared connections 26, 27 as is usual. Thedriving connection between the several rotary elements includes thetrain of gears 28, 29, 30, 31, s2, s3, s4.

A removable fixed cam 35 is arranged in position to open the sets ofgrippers 14 on the cylinder 12 for receiving the groups of sheets fromthe guides 24, 25. A movable cam 36 is controlled from a removable cam37, fixed to rotate with the cylinder 5. In

, the present instance this cam 37 is shown as a two-lobed cam. Incertain instances to be hereinafter set forth, this cam will be aone-lobed cam. The movable cam 36 is arranged to be brought into and outof position to hold the sets of grippers 14'open when they coact withthe sets of grippers 17.,

on the cylinder 15 to permit the said sets of grippers 17 to take thegroups of sheets in stead. of being taken by the sets of grip pers 14. i

A movable cam 38 is controlled by a removable cam 39, fixed to rotatewith the cyl inder 19. In the present instance this cam 39 is shown as atwo-lobed cam but inisome instances as will be hereinafter set forththis cam will be a one-lobed cam. The movable cam 38 is arrangedto holdthe sets of grippers 17 open at the time. of their coaction with thesets of grippers 14 when it is desired to have the sets of grippers 14take'the groups of sheets. A movable cam 40 is con trolled by aremovable cam 41, fixed to rotate with the cylinder 19. In the presentin stance this cam is shown as a two-lobed cam, but in some instances aswill be hereinafter set forth, it will be shown as a one-lobed cam. Thiscam 40 is arranged to control the operation of the sets of grippers 17at the time they coact with the sets of grippers 10 and 11 of thecylinder 5, for the transfer of either inserts or covers or both fromthe cylinder 5 to the cylinder 15.

Interconnected movable cams 42, 13 are controlled by a removable cam d4,fixed to rotate with the cylinder 6. In the present instance this cam 411 is shown as a twolobed cam, but in some instances as will hereinafterbe set forth, it will be a onelobed cam.

These movable cams e12, 413 are arranged in position to control theoperation of the sets of grippers 17 and 21 on the cylinders 15 and 19respectively at their point of coaction for the transfer of the productfrom the cylinder 15 to the cylinder 19.

The set of grippers 9 on the cylinder 6 are illustrated as tumbleractuated, the pin 15 being shown located in position to close thegrippers onto the cover or insert sheet, fed from the feeder 4 and thepin 16 being shown in position to open the grippers 9 for transferringthe cover or insert, as the case may be, to the cylinder 5.

A fixed cam 47 is arranged in position to operate the set of grippers 11on the cylinder 5 to take a cover or insert from the set of grippers 9on the cylinder 6. The set of grippers 10 on the cylinder 5 are shown astumbler operated, the pin .18 being arranged to open the grippers andthe pin 49 being shown in position to close the grippers onto the coveror insert, as the case may be, fed from the feeder A fixed cam 50 isarranged in position to open both the sets of grippers 10 and 11 attheir point of coaction with the sets of grippers 17 for transferringthe covers or inserts, or both, from the cylinder 5 to the cylinder 15.

The sets of side grippers 18 are controlled by a fixed cam 51 wherebythe side grippers may be closed onto the groups of sheets when it isdesired to open the head grippers for the reception of the extra sheets.

A fixed cam 52 is provided in position for opening the grippers 21 onthe cylinder 19 for delivering the products from the cylinder 19 to anysuitable folding mechanism. not shown herein.

1 will first describe the operation of the associating mechanismwhen thepreviously printed sheets are covers.

The groups of sheets from the main press may be collected on either thecylinder 12 or the cylinder 15. To the collected products from the mainpress the covers from the feeders 3 and 4 are successively fed and areassociated with their respective products at the center line between thecylinders 5 and From this cylinder 15 the so collected and associatedproducts are transferred to the cylinder 19 and from thence to any welllrnown or approved folding mechanism.

W hen the previously printed sheets are to be used as inserts, the firstgroup of main press sheets of each collection will be taken by thecylinder 12 and all subsequent groups together with the group taken bythe cylinder 12 will be taken by the cylinder 15. The insert-s fed fromthe feeders 3 and a are transferred by the cylinder 5 onto the emptysurfaces of the cylinder 15 which oc cur when the first groups of sheetsof successive collect-ions are taken by the cylinder 12. When thecollected groups of main press sheets are taken by the cylinder 15, theywill be taken on top of the previously printed insert which is alreadylocated on the surface of the cylinder 15, thus bringing the insert intothe center of the completed product when folded.

For a forty-eight page press arranged to deliver two twenty-four pageproducts, each associated with a four page cover, the first group ofmain press sheets is taken by the cylinder 12. This group of sheets,together with the final group of the collection is taken bv the cylinder15. The full collection is held in register by the set of side grippers18 on the cylinder 15, while the set of front grippers 17 are operatedto take the cover introduced by the cylinder 5. In this instance thecams 37, 39, 11 and 4: 1 arev two-lobed cams, as shown in Fig. 2.

For a forty-eight page press arranged to deliver a forty-eight pageproduct with a four page cover, the first three groups of main presssheets are collected on the cylinder 12. These sheets, together with thefinal group of the collection are taken by the cylinder 15. Thiscollection of main press sheets is held in register on the cylinder 15by the side grippers 18 while the front grippers are operated to takethe cover from the cvlinder 5. The above product can also be obtained bymaking all of the collections on the cylinder 15. This can beaccomplished by removing the stationary cam 35 so that the grippers 14:on the cylinder 12 will remain closed. In this instance the cams 37, 39,11 and 11 are one-lobed cams.

F or a forty-eight page press arranged o deliver a fort-yelp it pageproduct with both a four page insert and a four page cover. the firstthree grouiiis of main press sheets will be collected on the cylinder12, the in sert being introduced from one of; the feeders and depositedonto an empty surface on the cylinder 15. This cylinder 15 will nextreceive the full collection of the main press sheets on top of theinsert. The cylinder 5 will then feed the cover on top of the collectedproduct. In this instance the cams 37, 39, fl and i l will be one-lobedcams.

For a forty-eight page press arranged to deliver two twenty-four pageproducts, each associated with a four page insert, the first group ofsheets will be taken by the cylinder 12 and the insert will be depositedonto the empty surface of the cylinder 15 so that when the fullcollection of two groups of sheets is associated with the insert, theinsert will come in the center of the folded product. In this instancethe earns 37, 39, ll and 44 will be two-lobed cams.

To change the two-lobed cams into one lobed cams a half sectioncontaining onelobe of each cam is removed and a half section containinga concentric semi-circular cam groove, such as that shown in Fig. 5, isinserted.

By the term cylinder I wish to include any rotary means for conveyingthe sheets through. the prescribed paths and by the term grippers I wishto include any sheet engaging means suitable for this purpose.

It is evident that various changes may be resorted to in theconstruction, form and arrangement of the several parts withoutdeparting from the spirit and scope of my invention; hence I do not wishto limit myself to the particular embodiment herein shown and described,but
